December's a natural time to reflect on the past year and what we're grateful for, so the theme of this month's challenge is 'gratitude'.
It's up to you how you interpret the theme – it can be something you enjoy and appreciate in your daily life (a hobby, cups of tea, favourite books, sunshine, etc), or perhaps a person who you're very grateful to know. The more creative the better!
Check out our November shortlist if you need some inspiration.
The winner will appear in the magazine and receive a prize too!
To enter the competition on Instagram, you'll need to tag us @inthemomentmag and use the hashtag #ITMphotochallenge. You'll also need to tell us a little bit about your picture and why you feel grateful.
You have until 15 January 2018 to enter. Good luck!
